devif 6LoWPAN: The original, Contiki-based design used only a single buffer for reassemblying larger packets. This could be a problem issue for hub configurations which really need the capability concurrently reassemble multiple incoming streams concurrently. These was also a design issue in that the reassembly buffer could be corrupted by outgoing packets. The design was extended to support multiple reassembly buffers, each associated with the reassembly tag and source address. This assures that there can be be no corruption of the reassembly once it has started. 2017-08-26 10:00:47 -06:00

inet TCP Networking: When CONFIG_NET_TCP_WRITE_BUFF=y there is a situation where a NULL pointer may be dereferenced. In this configuration, the TCP connection's 'semi-permnanent' callback, s_sndcb was nullified in tcp_close_disconnect. However, other logic in tcp_lost_connection() attempt to use that callback reference after it was nullifed. Fixed in tcp_lost_connectino() by adding a NULL pointer change before the access. This was reported by Dmitriy Linikov in Bitbucket Issue 72. 2017-10-13 06:47:40 -06:00

socket net/socket: psock_send/psock_sendto: remove assert check for null psock and buf input pointers. Removes check as 'psock == NULL' altogether because that checked for later in psock_send and psock_sendto. Change null check for 'buf' so that it is handled same as in recvfrom.c (return -EINVAL instead of 2017-10-11 11:04:05 -06:00

utils sched/semaphore: sem_timedwait() is a cancellation point and, hence, cannot be called from within the OS. Created nxsem_timedwait() that is equivalent but does not modify the errno and does not cause cancellation. All calls to sem_timedwait() change to calls to nxsem_timedwait() in the OS. 2017-10-05 07:24:54 -06:00

net_initialize.c Addes support for read-only routing tables. Prior to this change, routing tables were only support in RAM and had to be initialized with explicit logic to add the necessary routes to the routing table. With this change, routes may be defined in the pre-initialized, read-only routing table provided by the board-specific logic 2017-09-28 09:04:31 -06:00
